i dont know asked some one else to asked
Liquid paraffin is used in the determination of melting point because it has a known and consistent melting point of around 40-60°C. This allows for a reliable reference point to calibrate and set the temperature of the melting point apparatus before testing other substances. Liquid paraffin also has a low volatility, ensuring that it remains stable throughout the duration of the experiment.
Melting point and boiling point determination can help in identifying unknown compounds by comparing the experimental values with known values in databases. A match can indicate the compound's identity. Additionally, the range of melting point and boiling point can provide information on the purity and molecular structure of the compound.
The term "melting point" is used to describe the temperature at which a substance changes from a solid to a liquid. The term "freezing point" is used to describe the temperature at which a substance changes from a liquid to a solid.
The melting point is the temperature at which a solid substance transitions to a liquid state. The drop melting point is a method of determining the melting point where a small amount of the substance is heated until it melts and then allowed to drop onto a solid surface to observe the melting point. Drop melting point is often used when the substance being tested has a high melting point or when observing the melting process is critical.
Fisher-Johns apparatus is mainly used to measure the boiling point

Paraffin is a commonly used material for determining the melting point of organic compounds because it has a well-defined melting point of 54-57°C and does not react with most organic compounds. This makes it a suitable medium for accurately measuring the melting points of various substances without interference.
Paraffin wax is a common flammable solid used to make candles. It is derived from petroleum and has a low melting point, making it ideal for candle-making.
The property of paraffin's high melting point is used to separate them from crude oil in a process called fractional distillation. Paraffin's high boiling point causes it to condense and separate from the other components of crude oil at different temperatures in the distillation column.
Paraffin oil is used in instruments as a lubricant due to its low viscosity and ability to reduce friction between moving parts. Although benzoic acid has a higher melting point compared to paraffin oil, it is not commonly used as a lubricant in instruments due to its acidic nature and potential reactivity with other materials.
Because the phase changes (solid and liquid, and even vaporization) are within safe temperature limits and the heat of fusion (enthalpy) is low compared to water -- i.e. it becomes solid again faster than freezing water. Unless you have some dry ice handy.
Melting point determination is not commonly used for inorganic compounds because many inorganic compounds have high melting points that are difficult to determine accurately using conventional methods, which can involve significant heating requirements and specialized equipment. Inorganic compounds can also have complex melting behavior, such as decomposition or phase transitions, that make determination of a precise melting point challenging. Analytical techniques like differential scanning calorimetry or thermogravimetric analysis are often more suitable for studying the thermal properties of inorganic compounds.

Oil baths are typically used for high-temperature melting point determinations, where the sample needs to be heated to a temperature above the boiling point of water. Water baths, on the other hand, are used for lower temperature melting point determinations, as water has a lower boiling point compared to oil.
i think its 100 --------- The range of the melting point is between 30 0C and 70 0C, depending on the material used. At a higher temperature the wax is thermally decomposed or ignited.
The melting point of candle wax varies depending on the type of wax used. Generally, paraffin wax (commonly used in candles) melts at around 120-150 degrees Fahrenheit (49-66 degrees Celsius). Soy wax, another common type, has a lower melting point of around 110-130 degrees Fahrenheit (43-54 degrees Celsius).
Finding the melting point of an organic compound can help with compound identification, purity assessment, and determination of its physical properties. It is commonly used in organic chemistry labs to confirm the identity of a compound and assess its quality for use in experiments or industrial applications.
